The housing 2O is 'provdedwith'he Q.,' :it one endand with the cha-mo et the opposite end thereof.

The valve 25 being so positioned within the housing that the same is capable of operating in the direction of the dow of the vapor or air and against the tension eing designed to retain the valve 25 in its normal seated position.

Arranged at the end of the housing 2O and opposite to the auxiliary pipe 17 vis the three-way valve casing 31 connected to the housing 20 through the means'of the pipe connection 32, and in which casin isv the three-way valve 34 having connecte to one of its ends the operating rod or'stem 35. Tapping the valve casing 31 at any suitable point as at 36 is the hot air inlet pipe 37 tapping the exhaust pipe 13 of the engine as at 38, and also tapping the valve casing 31 and at a suitablepoint for conjoined action with the inlet pipe 37 as at 39 is the vapor inlet pipe 40 which pipe is designed to pass through the inner wall of the radiator 5 and to project upwardly into the tube or stem 6 and slightly removed from the interior of the cap 7 of the radiator 5 as shown at 41. This construction of the vapor pipe 40 being so designed as to enter the upper portion of the radiator at a point Where the steam or vapor from the heated water therein collects and designed to convey the vapor to the three-way valve casing 31.

The three-Way valve 34 is preferably'cylindrical and is provided intermediate of its ends with the radial ports 32', 37 and'40, the ports 37 and 40 being the same size 'and approximately twice the diameter of the passages through the pipes 37 and 40 the port 32 being approximately three times the diameter of the passage through the pipe 32, (see Figs. 2, I3, 4, aud 5.) The position of the valve in Fig. 2 illustrates the ports of the valve 34 in registration and connectingr the leated air pipe 37, the vapor pi e 40 and thel pipe 32 leading into the cham er 23 of the automatic valve housing 20 and in this position the heated air passes from the exhaust pipe 13 through the pipe 37, the port 3T and through the port 32 into the valve chamber 28. The vapor from the upper porfrom the view shown in Fig. (i.

tion of the radiator 5 is conducted through the pipe 40, the port 40 and through tie port 32 thence to the valve chamber 23 and in this position of the valve the heated air and the vapor unite at the-juncture of the port 37 and the port 40 and are thereby commingled before the same are' assed into the valve chamber 23. In Fig. 3 t e valve 34 is shown as being sufficienti rotated to close the heated air pe37, an in this position only the vapor rom the radiator is trans mitted into the valve chamber 23. In Fig. 4 the valve 34'is shown in the position for closing the vapor pipe 40 and connecting the y heated air pipe 37 with the pipe 32- for transmitting the heated air into the chamber 23 and .the view shown in Figf illustrates" the valve as being rotated in a positioixrgor closing the passages of the pipes 3 2 37 and 40 for preventing the admissioneither the heated air or vapor should the condition of the fuel charge require these omissions.

The valve 34 has its operating stem 35 sufliciently elongated that the extremity of the same may be passed through the dashboard 2 and the indicator plate 45 arranged upon the inner. side of the dash-board 2 and through the upper portion of the indicator plate, the end of the operating stein 35 of the'valve 34 is provided with t e crank arm 46 which is provided at the end thereof with the handle 47 having arranged therein the plug 48 for engaging the a ertures 49 arranged at the lower end o the indicator plate 45, the plug 48 being outwardly d1- rected by the compression spring 50 within the handle 47 and surrounding the stern 52 ofk the plu 48 the stem projecting outwardly of t e handle 47 and is provided the free end thereof with'the Aknob 51 des'` signed to be grasped by the hand for releasing the plug 48 from its engagement with the apertures 49 when it is desired to revolve the rod 35 for actuatin the threeway valvt 34 as lshown ip- Fig'; 6. i is to be understood that the indicator plate 45 at the inner side of the dash board 2 is provided with a series of apertures 49 corresponding to thq varia tions of the position of the yalve 34 asl shown in Figs. 2, 3, 4 and 5 only one of the a'perF turesv wing shown in Fig. 6, the operation and co.isti'uction of which being obvious The operation of my device is deemed to be obvious in view of the foregoing description of the same. However, it is deemed expedient to here state that in the operation of my device the three-way valve 34 is manually set to admit either the vapor, heated air or both, r the valve may be set to prevent the admission .of both the va or and the heated air.
